A storage device includes a local memory, wherein data are locally stored, and a controller that is operative, in accordance with a reduction policy, to modify the data on the local memory, thereby freeing storage area on the local memory.
Legal claims defining the scope of protection, as filed with the USPTO.
1. A storage device comprising: a storage parameter database storing values of parameters; a local storage area storing data files; and a controller operative to: copy the data files from the local storage area to a remote data storage; automatically select a particular modification procedure from a plurality of modification procedures that includes at least three of lossless compression, lossy compression, beginning of file storage, icon representation, and interruption representation, wherein the selection is made based at least in part on the values of the parameters stored in the storage parameter database; and after the particular modification procedure is selected, modify the data files stored in the local storage area in accordance with the selected, particular modification procedure to effect a reduction policy that replaces each data file stored in the local storage by a corresponding data file representation.
2. The storage device of claim 1 , wherein the parameters include a date when a user is likely to use the data.
3. The storage device of claim 1 , wherein prior to the copying and the modifying, the controller is further operative to sort the data files in a queue for sequential execution of the copying and the modifying according to a predetermined priority order.
4. The storage device of claim 1 , wherein the local storage area and the controller are included in a subscriber identity module (SIM) card.
5. The storage device of claim 1 , wherein the values of the parameters specify a battery condition to be satisfied before the data files are copied.
6. The storage device of claim 1 , wherein the values of the parameters specify a time of day to copy the data files.
7. The storage device of claim 1 , further comprising a storage region operative to store the storage parameter database, wherein the storage region is distinct from the local storage area.
8. The storage device of claim 1 , wherein the controller is operative to automatically copy the data files from the local storage area to the remote data storage.
